We are embarking on an exercise to relocate a small production facility, electrical test area and a development lab. We are keen to consider all safety aspects in the design of the new area - e.g. access/egress, points of isolation, location of emergency stops, noise etc. etc.
I have been looking at the process of HAZOPS in order to consider risks and make recommendations to mitigate such risks at the design stage and wondered if anyone has embarked on a similar exercise which they could give me the benefit of their experience/advice on.
I am presently taking the stance that risk assessment and safe systems of work per se are not appropriate until we get to the construction, commissioning and operational stages, the key point being that we are still at the DESIGN stage.

Paul,
Interesting that you are consideering HAZOP study for an electrical lab & production facility.
As I understand HAZOP (never been involved in one), it is a method designed for the process industries (ie, petrochem, pharmaceutical, food). Does it apply well to your facility? Very interested to know.
HAZOP is normally applied at the design phase, but can be applied retrospectively.
There is plenty of published material on HAZOP.

I strongly support your view that OSH issues should be considered at the design stage. Though the classic Hazop was invented for Process design, the method has been successfully adapted in many other circumstances. A similar, less structured approach is 'What-if?'.
In either case, the key need is to assemble a small group which represents the full range of designers/users of the facility, and operating knowledge of similar operations. You need an experienced chair, and a good recorder/secretary. There is software available to help with this, and using a digital projector to let everyone see what is being discussed and recorded is a great help.
DON'T try to run a Hazop just based on reading about the technique, it does need training and experience to get good results, including getting the right atmosphere to allow the group to have and express creative thoughts.

Ian,
HAve you tried recording the HAZOP sessions by tape or digitally?

We have used a process before the construction or to support the construction and called it imaginatively a HAZCON. Essentialy focussed on; access/egress, provision of information, co-ordination, monitoring regimes, daily briefings etc
We dis this using a keyword list for the diffrent tasks involved so sim to a HAZOP.
